Membrane Separation System And Operation Method For Membrane Separation System
Abstract: The purpose of the present invention is to provide: a membrane separation system, which has high separation performance and long-term performance stability even under high recovery rate operation; and an operation method for the membrane separation system. The present invention provides a membrane separation system provided with a perforated water collecting tube, a plurality of separation membrane pairs, a supply-side flow passage member, and a permeation-side flow passage member, wherein a plurality of separation membrane elements in which the separation membrane pairs are wound around the perforated water collecting tube are connected. The plurality of separation membrane elements include first separation membrane elements and second separation membrane elements, wherein: the separation membrane pairs provided in the first separation membrane elements have a raw water supply part and a concentrated water discharge part that are respectively disposed at both end portions in the longitudinal direction of the perforated water collecting tube; the second separation membrane elements have, at end portions in a direction perpendicular to the longitudinal direction of the perforated water collecting tube, the separation membrane pairs having the raw water supply part and the concentrated water discharge part; and at least one of the first separation membrane elements is connected further upstream than the second separation membrane elements.
